Comparison Of Measured And Simulated Motion Of A Controllable Parafoil And Payload System, Nathan Slegers, Mark Costello Jan 2003

Comparison Of Measured And Simulated Motion Of A Controllable Parafoil And Payload System, Nathan Slegers, Mark Costello

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

For parafoil and payload aircraft, control is affected by changing the length of several rigging lines connected to the outboard side and rear of the parafoil leading to complex changes in the shape and orientation of the lifting surface. Flight mechanics of parafoil and payload aircraft most often employ a 6 or 9 DOF representation with the canopy modeled as a rigid body during flight. The effect of control inputs is idealized by the deflection of parafoil brakes on the left and right side of the parafoil. Using a small parafoil and payload aircraft, glide rates and turn performance were …

On The Use Of Rigging Angle And Canopy Tilt For Control Of A Parafoil And Payload System, Nathan Slegers, Mark Costello Jan 2003

On The Use Of Rigging Angle And Canopy Tilt For Control Of A Parafoil And Payload System, Nathan Slegers, Mark Costello

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Controllable parafoil and payload aircraft are controlled with downward deflection of left and right parafoil brakes. Lateral control is obtained by differential deflection while longitudinal control is created by collective deflection of the left and right side parafoil brakes. The work reported considers an alternative method to control parafoil and payload air vehicles by tilting the parafoil canopy for lateral control and changing rigging angle for longitudinal control. Using a nonlinear 9 degree of freedom simulation model, it is shown that canopy tilt provides a powerful lateral control mechanism and rigging angle provides a viable longitudinal control mechanism.

The Effects Of An Induced Negative Mood State On Ground- Based Learning In Student Pilots, Angela Sophia Wendell Oct 2002

The Effects Of An Induced Negative Mood State On Ground- Based Learning In Student Pilots, Angela Sophia Wendell

Master's Theses - Daytona Beach

The United States Department of Transportation and the Federal Aviation Administration's Aviation Instructors Handbook (D.O.T.) (1999) emphasizes that aviation students must maintain a healthy and positive state of mind in order to succeed at learning. Factors such as worry, lack of interest, physical discomfort, and anxiety are all listed as obstacles to a student's ability to learn successfully during flight instruction. In addition, numerous studies support the idea that a negative mood state will have a detrimental effect on learning. This study attempts to investigate the effects of an induced negative mood state on ground- based learning in student pilots.
